I work in senior housing and unfortunately this occurs often and can be very traumatizing the first time. Most hospices/hospitals have grief counselors available for these situations. She will definitely need more than nails, bath bombs and a day off. Perhaps she can utilize her sick leave for a few days to adjust to what she found, but it will stick with her for a while. Maybe not send her into units alone or better yet, when tenants are not seen or heard from over several days, I would call the non-emergency police/fire department number to conduct a health & safety check, so they find the tenant not your staff.

Oh wow. Our PD allow us to stand outside the door while they go in

The police were called. They refused to go in without the agent.

That's my biggest fear, is to find someone. Thankfully our company policy is to not do wellness checks ourselves. If there is a legit concern the police are called to do that

Let her know she can talk to you, but don't push her. My first was rough, and I tried not to think about it, the more ppl pushed me to talk the worse it was. Give her a day off, and I second the scentsy idea.

Does the company have an EAP? People process events differently. She may say she's fine, and even seem fine, but a person to call if it sneaks up on her would be good. For me, I've found a good cry and a glass of wine helps.
